Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The invention relates to a pachinko ball dispensing device, and in particular to a pachinko ball alignment mechanism for aligning irregular pachinko balls. Regarding.

(Prior Art) A pachinko ball dispensing device that dispenses a predetermined number of pachinko balls generally has a hopper that stores a large amount of pachinko balls in an irregular manner in the upper part of the device, and a hopper that is arranged in an inclined manner from the bottom end of the hopper. It has a continuous ball path for aligning pachinko balls in an irregular state, and a dispensing mechanism provided downstream of the ball path for discharging a predetermined number of pachinko balls in an aligned state, Irregularly shaped pachinko balls stored in the hopper flow into the ball passage due to their own weight, and while the pachinko balls roll through the ball passage due to their own weight, they are divided into multiple rows in the horizontal direction, and also in the height direction. They are arranged in a line and arranged in an aligned state. Then, the dispensing mechanism is operated based on a predetermined dispensing command to dispense a predetermined number of aligned pachinko balls.

(Problem that the invention attempts to solve) However, with the above conventional pachinko ball dispensing device,
To bring irregular pachinko balls into alignment,
Pachinko balls are rolled in the ball passage by their own weight,
The structure is such that the horizontal direction is divided into multiple rows, and then each row is restricted to a single row in the height direction while rolling further, so the flow of the pachinko balls depends only on the weight of the pachinko balls themselves. Since the force acting on the rolling pachinko balls was always in the same direction, if the pachinko balls compete with each other or if the center of the pachinko ball hits the edge of a partition wall that divides the ball path, the pachinko ball will roll. The force acting in the direction of
There was a problem with the ball clogging. If the ball jams in this manner, problems such as a predetermined number of pachinko balls not being ejected or being unable to eject the balls will occur.

On the other hand, once a blockage occurs, the only way to clear the blockage is to apply an external shock such as shaking or hitting the entire device, or to open the device to clear the blockage. There is no means to clear the blockage, and as a result, not only is it time-consuming to clear the blockage, but the device may also be damaged if an external impact is applied.

The present invention has been made with the aim of improving the problems of the prior art as described above, and provides a pachinko ball alignment mechanism in a pachinko ball dispensing device that can always keep pachinko balls in an aligned state. It is in.

[Structure of the idea]

(Means for Solving the Problems) In order to solve the above-mentioned problems of the prior art, the present invention arranges the pachinko balls that are irregularly stored in the hopper and then counts them using a dispensing means. In a pachinko ball dispensing device for dispensing pachinko balls, a partition wall is provided in an inclined manner from the lower end of the hopper and partitions the width of one pachinko ball in the lateral direction to form a plurality of rows of partition passages; a ball alignment path having a height regulating member that gradually regulates the height to the height of one pachinko ball; and a ball alignment path provided rotatably at a lateral position corresponding to the partition wall, and It is equipped with a plurality of eccentric discs that guide pachinko balls in a position to a partitioned passage, and a plurality of eccentric rollers that are rotatably provided above the partitioned passage in correspondence with the partitioned passage and prevent the pachinko balls from overlapping. The game machine is characterized in that irregular pachinko balls are guided into an aligned state both in the lateral direction and the height direction by the rotation of the eccentric disk and the eccentric roller.

(Function) With the above configuration, pachinko balls in an irregular state are divided into a plurality of compartment passages by the rotation of the eccentric disc, and the height direction of the pachinko balls in the division passage is divided by the rotation of the eccentric roller. This prevents the pachinko balls from overlapping in the height direction, and thereby the pachinko balls are forcibly guided in an aligned state in the lateral and height directions, thereby preventing the balls from clogging in the passage.

A gear 23 is fixed to the other end of the shaft 17, and this gear 23 and a gear (not shown) at the end of the shaft 19 of the partition disk 18 are rotationally connected via a gear train, and the partition disk 18 is adapted to be rotated in the direction of the arrow in FIG. It goes without saying that other suitable means may be used as these rotation transmitting means.

Next, the operation of the above embodiment will be explained.

When a large number of pachinko balls 1 are thrown into the hopper 2, the pachinko balls 1 flow into the lower end outlet part 2A due to their own weight in an unaligned state, and the lower first stage of the pachinko balls 1 is divided into the partition wall 11 of the upper ball alignment passage 3A, 11...
It enters the partitioned passages 10, 10 between and rolls downstream to the partitioned passages 10, 1 of the lower ball alignment passage 3B.

When the solenoid 7 is momentarily excited by the throwing command, the locking member 9 is removed from the notch 6 and the counting wheel 4 is unlocked, and the weight of the pachinko balls 1 turns the counting wheel 4 to perform throwing. It can be done. Counting wheel 4
When it rotates half a turn, the locking member 9 engages with the next notch 6, the counting wheel 4 is locked, and the pachinko balls 1 stop being thrown out. As a result, a certain number of pachinko balls 1
The casting is completed.

On the other hand, as the pachinko balls 1 are thrown out, the pachinko balls 1 in the ball alignment path 3 flow, but the pachinko balls 1 that enter the hopper 2 in an unaligned state from the lower end exit portion 2A are held by the eccentric discs 15, 15. ...and the eccentric rollers 16, 16..., the eccentric rotation of the eccentric disks 15, 15... will cause the partition walls 11, 11... The pachinko ball 1 located at
Furthermore, as shown in Figure 5, the pachinko balls 1 flowing in two stacks are pushed down by the eccentric rotation of the eccentric rollers 16, 16, and as shown in Figure 6, the pachinko balls 1 in the upper row are pushed down by the pachinko balls 1 in the lower row before and after. balls 1,1
They are pushed in between, breaking the two-tiered state and making it easier to become one.

Therefore, while passing through the eccentric disc 15 and the eccentric roller 16, the pachinko balls 1 are in a state where they tend to form one row and one stage in each section passage 10, 10, and then pass through the sectioned circle. Boards 18, 18...
. . , while the balls are fed into the divided passages of the lower ball alignment passage 3B, they are arranged in one row and one stage for each of the divided passages 10, 10, . . . .

In this case, as in the illustrated embodiment, the eccentric disk 15,
By making the phase of the eccentric rotational motion of the eccentric rollers 15, 16, 16, and so on different from those of the adjacent ones, there is a margin in the lateral direction when aligning the pachinko balls 1, so that the pachinko balls 1,1
This is advantageous in preventing comrades from competing horizontally.

[Effect of idea]

As explained above, according to the present invention, pachinko balls in an irregular state in the ball alignment path are laterally distributed by the rotation of the eccentric disk and guided to a plurality of compartmented passages, and the balls are guided into the compartmented passages by the rotation of the eccentric roller. By eliminating the overlapping of pachinko balls, it is easy to form a single layer, and the irregularly flowing pachinko balls are forced to be aligned horizontally and vertically, so that they can be easily aligned in the ball path. can reliably prevent clogging. Further, since there is no need to apply an external impact as in the conventional case, there is no need to damage the device, and various effects such as eliminating the need to open the device to clear a blockage can be obtained.
